甲醇中低温着火延迟时间的计算模型
Computational Model of Low-to-Intermediate Temperature Ignition Delay Time for Methanol-Air Mixture

查看参考文献20篇

文摘 研究了甲醇在中低温条件下的氧化特性,通过对详细反应机理的分析,得到一个九步的骨干机理,在1,500,K下其着火延迟时间预测值与详细机理的预测值基本一致.通过理论分析着火感应期内占主导作用的自由基行为,最后得到了一条能用于估算甲醇中低温着火延迟时间的显式公式.该公式显示甲醇在中低温下的着火延迟时间主要取决于CH_3OH+HO_2→CH_2OH+H_2O_2的反应速率.该反应对甲醇在中低温下氧化特性有重要的影响.
其他语种文摘 The oxidation characteristics of methanol-air mixture at low-to-intermediate temperatures were investigated numerically in this work.Based on the analysis of the detailed kinetic mechanism of methanol,a nine-step skeletal model was developed and validated by comparing the computational ignition delay time under 1,500,K with that from detailed mechanism.With further analysis of auto-ignition behavior in a homogeneous adiabatic system,an explicit formula for ignition delay time was derived,which had a simple form and showed good agreement with numerical results.It was indicated that the ignition delay time of methanol-air mixture at low-to-intermediate temperatures was mainly controlled by the reaction rate of CH_3OH+HO_2 →CH_2OH+H_2O_2,which has a dominant effect on the oxidation behavior of methanol within this temperature range.
